Method and system for determining air turbulence using bi-static measurements

摘要

A method and system for determining atmospheric disturbances or turbulence is disclosed. The system includes a plurality of sensor arrays, including at least one sensor element, distributed in a predetermined manner. Each of the sensor elements is in communication with a corresponding receiving system that is operable to receive and process energy received from the aircraft. A determination is then made regarding air turbulence by determining a rate of change of signal phase among selected sets of signals received at the receiving systems. A turbulence map is then determined from the determined rate of change of the phase and the angle of the received signal. When the rate of phase change exceeds known levels an indication of turbulence is made.
